Corporate risk hedging with forward contracts increases value by reducing incentives to underinvest. This occurs because the hedge decreases the sensitivity of senior claim value to incremental investment, allowing equity holders to capture a larger portion of the incremental benefit from new investment. Hedging also allows the firm to credibly commit to meet obligations in states where it otherwise could not, which improves contract terms the firm can negotiate with customers, creditors, and managers. These benefits cannot be duplicated by individual hedging, and each result holds independent of agents' risk preferences.

An algorithm is described that prices European average options. The algorithm is tested against Monte Carlo estimates and is shown to be accurate. The speed of the algorithm is comparable to the Black-Scholes algorithm. A closed-form solution is derived for European geometric average options.

This paper develops a valuation formula for multi-period stochastic cash flows consistent with rational risk-averse investor behavior and equilibrium in securities markets. It shows that the CAPM does not have to be sequentially applied in discounting of the cash flows of multi-period projects, and a single beta can be used to measure the riskiness of an uncertain income stream. Hence, a multi-period project is priced as if it offers a single payment. The formula uses a set of assumptions that is slightly more restrictive than the minimum set Constantinides (1980) uses to produce the multi-period version of the CAPM. This paper also demonstrates that, under certain assumptions, covariances of stochastic cash flows with changes in the term structure may be sufficient measures of the cash flows' riskiness.

This paper provides an imperfect information explanation for the existence of bank loan commitments when both the bank and the potential borrower are risk neutral. The borrower is assumed to have access to a two-stage investment project wherein the investment required in the second stage is not known at the outset. The unknown investment requirement is revealed to the borrower, but not to the bank, at the beginning of the second stage. If the investor borrows at the beginning of the first stage, the realization at the beginning of the second stage might prompt a default in a situation where the project yields positive net present value. The reason is that the borrower does not regard the first-stage investment as a sunk cost. We show that a two-stage contract resembling a loan commitment can solve this under-investment problem.

The role of fiduciaries with conflicting interests has received considerable attention recently. The purpose of this paper is to analyze the role of a fiduciary casting votes under conflicting interests in proxy contests that seek to control the corporation and those waged solely for the purpose of deciding an issue. By deriving comparisons across types of contests, we provide implications concerning differences in success probabilities and resolution effects for the two types of contests. The empirical verification (refutation) of such effects would provide insight regarding the (ir)relevance of fiduciary conflict-of-interests in proxy contests.

This study examines the valuation consequences of control-related outcomes that follow toehold acquisitions. We find evidence that toehold acquisitions facilitate value enhancing control transfers. The types of control transfers not only include takeovers, but also internal mechanisms, such as proxy fights and management turnovers. We find that toehold targets experiencing such control transfers exhibit an abnormal increase in share value, while those not experiencing such control transfers exhibit an abnormal decrease in share value. The results suggest that the positive valuation effect associated with toehold acquisitions reflects the expected benefits of subsequent control transfers.

This paper presents a model in which managers of firms that are takeover targets use debt-financed share repurchase to bond themselves to reduce perquisite consumption and increase investment in the firm. The resulting value increase makes the firm a less attractive target. The optimal level of share repurchase is the result of a trade-off between the benefit of a reduced probability of takeover and the cost of an increased probability of bankruptcy. Unlike earlier explanations of defensive repurchases, which are based on information signalling or control of voting rights, this explanation is independent of the extent of shareholding by target management.

This paper examines cash management bill announcements in an event study framework and finds that segmentation in the Treasury bill market is widespread and not limited to bills maturing across month-ends. Announcements of cash management bills, which represent unexpected additional supplies of outstanding Treasury bills, cause the yields on these bills to rise significantly relative to yields on adjacent maturity bills. This paper also finds, consistent with other studies, that segmentation is greater at the short end of the bill market.

In this paper, we demonstrate that the conflicting results found in the literature of tests of the unbiased forward rate hypothesis (UFRH) depend upon the econometric specification used as well as differences in the time period of estimation. It is established that the time series properties of spot and forward exchange rate data rule out certain econometric specifications used to test the UFRH. Specifically, we find that both spot and forward exchange rates for the U.K., Germany, Japan, and Canada have unit roots and are cointegrated. We also find that the co-integrating parameter in the regression of realized spot on forward rates for each currency is approximately one, implying that researchers who use this specification to test the UFRH may falsely accept the hypothesis simply because of the specification used in the test. Using an alternative error correction specification, we find that the UFRH is resoundingly rejected for all currencies and that the coefficients in this specification exhibit temporal instability. More importantly, we find that the evolution of the estimated parameters is becoming increasingly inconsistent with the UFRH with the passage of time. We conclude the paper with an investigation into potential causes for the gross violation of the UFRH.

This paper uses a time-state-preference valuation model to examine how the firm's choice of technology and production method affects its equilibrium level of risk and, as a result, the firm's cost of capital. A fixed and flexible method of production is analyzed for a firm using a Cobb-Douglas production function. In both cases, it is found that risk and the cost of capital decrease with the level of capital intensity. Implications are drawn for the specification of empirical tests of the determinants of risk.

When futures contracts are settled with respect to underlying asset prices, received theory suggests that the differences between futures prices and implied forward prices (from the term structure) are strictly due to marking to market, ceteris paribus. Empirical evidence appears to indicate that such differences are small for contracts with short maturities. What happens when the futures contract settles to yields implied by future prices of underlying assets? The Eurodollar futures contract, which is the most actively traded futures contract in the United States, settles to yield as opposed to prices. This unique settlement feature is shown to imply that the implied forward prices from the LIBOR term structure should differ from the futures prices even in the absence of marking to market. Differences due to marking to market effect are small: they are shown to vary between 2 to 45 basis points (less than one-half percent of futures prices). On the other hand, differences between implied forward prices and futures prices are shown to be relatively large.

This paper tests whether there is a difference in the stock price reactions to industrial straight debt offerings of different risk. Using bond ratings at the time of announcement as a measure of risk, we find that there is no monotonic relation between stock price impact and rating and no statistically significant difference across risk classes, even though the sample includes low-rated debt issues from recent years. This confirms earlier evidence on straight debt issues, but differs from the evidence on convertible securities. The paper also finds that the results for straight debt are not affected by shelf registrations or by the issuing firms' involvement in merger and acquisition-related activity.

This paper assesses the ability of financial statement variables to forecast sensitivities to systematic risk factors generated by a multifactor, macroeconomic forces model. Forecasts of beta derived from financial variables are shown to outperform naive, random walk forecasts, although Bayesian-adjusted betas perform as well as the financial variables model.

This paper tests for seasonal patterns in corporate bond returns using the Dow Jones Composite Bond Average. Each seasonal pattern documented for equities is investigated. For the period 1963–1986, corporate bond returns exhibit January, turn-of-the-year, and weekof-the-month effects, but no significant day-of-the-week or turn-of-the-month effects. In contrast, for the S&P 500 stock index, the turn-of-the-month and day-of-the-week effects are highly significant, but the week-of-the-month effect is less significant, and the January and turn-of-the-year effects are insignificant. The behavior of an equity index constructed using companies in the bond index is similar to that of the S&P, except the turn-of-the-year effect is significant.

Previous studies in the valuation of American options apparently undervalue the right of early exercise. This study uses actual prices from the CBOE's S&P 100 option instead of model-generated values. Deviations from the theoretical put-call parity relationship are caused by the possibility of early exercise. These deviations are used to infer the value of early exercise. The actual value of early exercise is both statistically and economically significant. As expected from theoretical considerations, the value of early exercise for put options is greater than for call options.

We examine the price behavior of the firm's common stock associated with cancelled straight debt offerings. Excluding utilities, we find negative excess returns associated with offering and cancellation announcements. Further, the stronger withdrawal reactions we find, when the funds were to be used for capital expenditures, may signal a decline in profitable investment opportunities. These results are consistent with Miller and Rock's (1985) hypothesis.

This paper corrects the bond option formula presented by R. Rabinovitch ((1989), Equation (10)). With just one state variable driving the economy, the formula should be the same as the ones presented by Jamshidian (1989) and Chaplin (1987).

This paper derives the optimal hedge of an uncertain (unknown quantity) future foreign currency cash flow. This more general optimal hedge includes the traditional hedge for a certain (known quantity) future foreign currency cash flow as a special case. The optimal hedge is found to be unbounded and determined by firm-specific conditions, including the variance of the expected cash flow, and the correlation of that future cash flow with actual exchange rate movements. Simulated optimal hedge values are found for U.S.-based multinational firms possessing S/Dm cash flows, using exchange rate data for the 1981–1987 period. Special cases in which the optimal hedge ratio equals zero and one also are identified, and we show that cash flow uncertainty can strongly affect the effectiveness of hedging.
